With my Polaroid glasses I could clearly see the trout holding at the end of a bed of aquatic weeds. It was not a remarkable trout for that particular stream; a brown trout probably about fourteen inches long. Occasionally it would tip up and appear to take something from the surface and then drop back down into its holding position. Looking up and downstream I did not see any other fish working so I thought I would take a shot at this seemingly easy fish. An hour or so later the trout was still there, still tipping up and eating something but I never did figure out exactly what.
